About This Project
The preheater tower is a tall, multi-stage cyclone system that uses hot exhaust gases from the kiln to heat raw meal powder, removing water and starting the calcination process before it enters the kiln, significantly improving energy efficiency, increasing production, and reducing fuel consumption by recovering heat and enabling continuous, high-capacity clinker production.
The tower reached almost the height of 110m with a slenderness ratio of 5:1. Four massive concrete shear wall columns and perimeter concrete beams were slip formed to a height of 90m and after that, a steel structure was anchored on top. Internal steel platforms were anchored to the perimeter concrete beams to support the cyclones and equipment.
The foundation sits on massive piles at each of the four corners of the structure.
